Methods, systems and machine readable tangible storage media that integrate an application store in a user device. In one embodiment, a selected document that cannot be used as selected triggers a request to an application store server to determine an availability of applications to use the document as selected. The user device enhances the display of the document selection interface to allow the user to display an application store interface to purchase the application. The purchased application is downloaded and installed on the user device, and the user is optionally apprised of the progress of the purchase with an animated icon representing the application “flying” from the application store interface and “landing” in a dock area within the display on the user device when ready for subsequent launch. Other embodiments are also described.
